The 3SGTE Cylinder head has been proven many times over to have excellent power capabilities with no expensive porting or head work. The ATS Racing cylinder head package has been developed over many years, from experiences with our customer cars and our own personal vehicles. This is the head package used in these 700 RWHP builds: The 1st graph is a Precision 6262 at 45psi boost, on an ATS 2.2L stroker, ATS cylinder head and GSC 274 cams, running an Autronic SMC tuned in-house at ATS.
The second graph is an older ATS build with Greddy T88, ATS 2.2L long block.
